According to a report by Fox23.com, more and more thieves are walking into QuikTrip convenience stores and exiting without paying for six-packs of beer. Although these thieves think they are getting away with the crime, many are being arrested after the fact.

A prime example is James Davis III, whom Tulsa, Okla., law enforcement officials arrested last week for allegedly stealing beer nearly a dozen times. "People think they're getting away with it, and they're really not. We just haven't caught up to them yet. We've got their surveillance, we've got the technologies and we're identifying them," Maj. Shannon Clark, with the Tulsa County Sheriff's Office, told the news outlet.

QuikTrip spokesman Mike Thornbrugh would not share specific details about the security upgrades the convenience store chain has made recently, but he did note that QuikTrip’s security measures are much more advanced than criminals think.

"They've taken eight, nine guys off the streets that we know have stolen probably about 80, 90 times from us," Thornbrugh said, referring to Tulsa law enforcement officials. "Who knows how many times they've stolen from anybody else."

Thornbrugh said he knows the c-store retailer’s security upgrades are working based on recent subsequent arrests made using the surveillance footage. Tulsa-based QuikTrip Corp. operates more than 650 c-stores.
